1996 CHEVROLET S10 engine coolant

Downloaded from www.Manualslib.com manuals search engine When you decide it’s safe to lift the hood, here’s what
you’ll see:
If your vehicle has air conditioning, the auxiliary
electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools away from
--1 any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t
do anything else until it cools down.

B. Radiator Pressure Cap
C. Engine Fan

Downloaded from www.Manualslib.com manuals search engine The coolant level should be at the ADD mark. If it
‘ isn’t, you may have a leak in the radiator hoses, heater
hoses, radiator, water pump
or somewhere else in the
cooling system.
A CAUTION:
Heater and radiator hoses, and other e Jne
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine if there is a leak.
If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
I
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, start the engine again. See
if the fan speed increases when idle speed is doubled by
pushing the accelerator pedal down.
If it doesn’t, your
vehicle needs service. Turn off the engine.

Coolant Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
ADD, add a 50/50 mixture of clean water
(preferably distilled) and DEX-COOL TM (orange-colored,
silicate-free) antifreeze at the coolant recovery tank. (See
“Engine Coolant” in the Index for more information.)
k!, CAUTICJ:
Adding only plain. water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you
or
others could be burned. Use a 5W50 mix of clean
water and
DEX-COOL TM antifreeze.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mix.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn
if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at
ADD, start your vehicle.
If the overheat warning continues, there’s one more
thing you can try. You can add the proper coolant mix
directly
to the radiator, but be sure the cooling system
cool before you do it.

1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap and
upper radiator hose, is
no longer hot. Turn the pressure
cap slowly counterclockwise until
it first stops. (Don't
press down while
turning the pressure cap.)
If
you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.

of the filler neck.
4. Then fill the coolant recovery tank to the ADD mark.
5. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap
off.

Downloaded from www.Manualslib.com manuals search engine 6. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine fan.
7. By this time the coolant level inside the radiator
filler neck may be lower. If the level is lower, add
more of the proper mix through the filler neck
until
the level reaches the base of the filler neck.
8. Then replace the pressure cap. At any time during
this procedure if coolant begins to flow out of the
filler neck, reinstall
the pressure cap. Be sure the
arrows on the pressure cap line up like this.

To open the hood, first pull
the handle inside the vehicle
on the lower left side of the
instrument panel.

go to the front of the vehicle and release the
secondary hood release. Lift
the hood, release the hood prop from its retainer and
put the hood prop into the slot in the hood. You may
have a lamp that comes on when you lift the hood.

A CAUTION:
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.
